Profile of Pain and Unpleasant Sensations in Patients With Referred Pain

Brief Summary:

This feasibility study primarily aimed to assess the technology acceptance and usability of a pain tracking software in patients with spinally referred chronic pain. The secondary aim was to assess the fluctuations in pain intensity and distribution, using the pain tracking software during a 3-month period. Additionally, the study aimed to explore the patients' behavior when self-reporting pain when given the opportunity to use a variety of pain quality descriptors, such as tingling, burning and stabbing.

Patients with spinally referred chronic pain will be recruited to participate. Participants will be asked to use a pain tracking software to create weekly pain reports for a 3-month period. These pain reports consist of pain drawings and intensity scales. Additionally, patients will complete baseline disability and pain catastrophizing online questionnaires. The project does not affect treatment or does not offer any intervention.

Primary Outcome Measures :
  1. Change in pain extent for 3 months [ Time Frame: 3 months ]
    Changes in pain extent as measured by the number of pixels drawn in digital pain drawings, at weekly intervals.

Secondary Outcome Measures :
  1. Change in pain intensity for 3 months [ Time Frame: 3 months ]
    Changes in usual and current pain intensity as measured by a Numerical Rating Scale, at a weekly interval.

  2. Changes in pain location for 3 months [ Time Frame: 3 months ]
    Changes of the location of pain measured by appearance and disappearance of pain in different body regions.

  3. Disability levels at baseline [ Time Frame: Baseline ]
    Description of disability levels as assessed by the Oswestry (if pain located in back) or the Neck Disability Index (if pain located in neck) online questionnaires.

  4. Pain Catastrophizing score [ Time Frame: Baseline ]
    Scores obtained from an online Pain Catastrophizing Scale (PCS) at baseline

Other Outcome Measures:
  1. Demographic information [ Time Frame: At baseline ]
